It was the first large-scale study to look at precancerous polyps in this age group.

Call me crazy, but if this is the first study of this age group, then how can they claim a "troubling increase" in the polyps?

Perhaps the people who chose to take colonoscopy before age 45 are a specific subset, not characteristic of entire population.... so recommendations based on this “a postiori” analysis are skewed/not valid.

I say this because I chose to take the colonoscopy at age 45 because grandmother was diagnosed & treated for colon cancer.
